Thank you for clarifying this for me. I was originally trying to think of ways to run two levels of service areas and I thought of using the polygons as barriers but I wasn't sure if that was the correct method. I'll give this suggestion a try. Thanks Jay!

I have multiple points on my map that I need to create service areas for. Each point has their own calculated break value. E.g. one point has a attribute-created break of 10 while another has a value of 6. I need to run an analysis so that a service area is created around each point without overlapping polygons. However, when I calculate around a dense region of points, the points with a lower value seem to overtake and don't allow for those points with a high value to create a proper boundary. I've included an image here. The polygon in red has the highest value of 7000, while the surrounding gray polygons have values of 3000. How do I give the points with higher break values priority to be the largest? [ATTACH=CONFIG]26195[/ATTACH]

I have a building footprint that shows the setback area as open-space (green space), however depending on the shape of the building, I want to remainder of the building footprint to become open space as well. Is there any way to do this? I have included an image which hopefully explains what I want to do. Thanks.[ATTACH=CONFIG]23618[/ATTACH] My code is: Parcel --> #create parcel from outline
setback (distanceStreet)
{ street.front: OpenSpace | remainder: SubParcel}
SubParcel --> #divide parcel into subparcel for open space and building space designation
setback (distanceBuilding)
{ street.back: OpenSpace | street.left : OpenSpace | street.right : OpenSpace | remainder: Footprint}
OpenSpace -->

Hello, I am trying to follow the 3DCity workflows, however they are very unclear. The Building Analysis workflow refers to Part 1 and 2 of the series, however I can't find this anywhere on the workflow site. It also says that we should start CityEngine and load the "3D City Creation" project from parts 2 and 4! If somebody could please direct me to whatever this tutorial is referring to I would appreciate it. Thanks.

Hi skimmer, No solution yet. I've been trying to tweak spider tools and my data to assist in the calculations, but as I too have many many points (about 4000), it is impossible to divide up the data in such a way that I can calculate all the routes and still manage all the layers. I'll keep you updated if any progress is made. Please do the same for me. Thanks, David P.S. I have looked into Network Analyst quite a bit but from what I've seen it doesn't help with this issue. I'm not sure if anybody else is able to confirm this..

Hello, I am trying to create line segments between different cities in the world. I've previously used Spider Tools: http://arcscripts.esri.com/details.asp?dbid=14908 and it worked quite well when I was mapping from one main point to many others. e.g. A -> B, A -> C, A -> D, A -> E.... My issue now is that I have connection cities in between, so I need to map A --> B A--> B --> C A --> C --> D A --> B --> E --> F ... Does anybody know of a way I can get these lines to automatically be created? It seems like it would be relatively simple - just connecting the dots based on location, but I can't find anything that would do this for me. Thanks!
